Many webmasters work with pharmacy traffic, and here are the basic methods of turning this traffic into money:
1) Pay Per Click Programs
2) Pay Per Sale Programs

Each of these methods has its pros and cons. Using the first option a webmaster gets a fixed sum for every click made by surfers, whether they make a purchase or not. The price can vary heavily from $0,2 to $9 per click. Using the second option a webmaster gets credit when a user makes a purchase. The usual commission is about 30% of the price, which is up to 20-60$. Repeated purchases are the main advantage of the second option. I.e. a person makes an order and gets the package in time - which makes him likely to buy from this shop again. About 10% of the customers return for another pack. The main thing to take care of when you work with Pay Per Sale program is filtering solvent traffic:
1) Geotargeting. Use only traffic from solvent countries and those countries where the shop ships its goods.
2) Analyzing the search query. If a user searched for a certain pill using words like buy, online, shipping, cheap, discount, fedex, without prescription, city name + any of these, he’s likely to buy. On the other hand, if the query includes side effects, pic, overdose, information and similar wording, send this visitor to a PPC and remember to add a banner to your feed - maybe he’ll finally buy something.
3) If a search query includes “free shipping”, send him to the site with free shipping (shipping costs included into the price). Same thing with FedEx etc.
4) Place a search field on the pages of your shop so that a user can search for a product not sold by you using a PPC.
